CMF-OS is frequently misdiagnosed on a radiological examination and biopsy, even after the initial operation. Its treatment is a controversial issue due to its low-grade classification and actual high-grade behavior. Case presentation: We retrospectively reviewed the medical charts of more than 2000 osteosarcoma patients between 2008 and 2019; 11 patients with CMF-OS were identified, of which six patients were treated by our institution with complete clinical characteristics, including treatment and prognosis, radiological and pathological features were reviewed. Three males and three females with a median age of 46 (range 22–56) years were pathologically proven to have CMF-OS. The radiological presentation of CMF-OS is variable, thus radiological misdiagnoses are common. However, one must not ignore a malignant radiologic appearance. The most distinctive pathological feature conferring the diagnosis of CMF-OS is the presence of osteoid production directly by the tumor cells under a chondromyxoid fibroma (CMF)-like background. Differential diagnoses based on comprehensive data from CMF, LGCO, chondrosarcoma (CHS), conventional osteosarcoma (COS), etc., are needed. All patients were treated with an operation and chemotherapy, and one patient received additional radiotherapy.

(e-mail: [email protected]). Abstract Chondromyxoid fibroma (CMF) is an exceedingly rare tumor that represents less than 1% of all primary bone neoplasms. Occurrence in the facial and cranial bones is extremely rare and frequently misdiagnosed. Case Reports We report two cases of CMF, one in the sphenoclival skull base and the other involving the parietal bone in two young female patients. Excision was performed in both cases. Presenting symptoms, treatment, and follow-up are reported. Methods A retrospective review of the literature on cranial CMF was performed. The location, demographics, presenting symptoms, and treatment of all calvarial and skull base CMF cases published since 1990 are summarized. Discussion In our literature review, we found 67 published cases of cranial CMF. Mean age of all calvarial and skull base CMFs at diagnosis was 38.2 years old.

  • Musculoskeletal Tumor Information
    Tumor Information Bone Tumors Soft Tissue Tumors Bone Tumors Bone tumors are a rare cause of musculoskeletal pain but should always be considered in the patient with otherwise unexplained pain. Most bone tumors present with pain and/or a mass. Care must be taken to ensure the correct diagnosis is made, and early consultation with an orthopaedic oncologist is advised to avoid potential complications. In general, these tumors are best treated at a referral practice that specializes in bone tumors. Benign Presenting symptoms Benign bone tumors can have a wide variety of presenting symptoms; in general, benign bone tumors present with pain. Tumors can occur in any bone, and can occur in all age groups. In general, these tumors are a rare cause of musculoskeletal pain, but should be considered when the diagnosis is in question. Often, benign tumors are found incidentally when patients are imaged for other reasons (i.e., a football player hurts his knee and gets an X- ray to rule out fracture; a suspicious tumor is seen). These are usually benign tumors, but need to be carefully evaluated by an orthopaedic tumor specialist. Diagnostic Imaging Imaging is necessary to diagnose a bone tumor. Often, multiple tests are ordered, but must be evaluated carefully by an orthopaedic tumor specialist to make sure that the most accurate diagnosis is rendered. X-Ray Usually done in the office, this is the most basic imaging test. Plain X- rays can provide essential diagnostic information, and must be of high quality. It is not uncommon to have to repeat these in order to make sure a high quality digital image is obtained.

Department of Otolaryngology - Head and Neck Surgery, Indiana University School of Medicine, Indianapolis, USA Corresponding author: Alhasan Elghouche, [email protected] Abstract Chondromyxoid fibroma (CMF) is a rare, benign neoplasm of the chondroid, myxoid, and fibrous tissue. It characteristically affects the lower extremity long bones, although it may rarely arise within the craniofacial skeleton. We report the diagnosis and management of a 31-year-old male with a large, incidentally discovered CMF originating from the sphenoid sinus. A subsequent review of the literature reveals the need to differentiate from more aggressive neoplasms, such as chondrosarcoma and chondroma, which share radiographic features. A histopathologic examination is crucial for proper diagnosis and treatment. We discuss clinical sequelae, highlight the importance of a thorough pre-operative evaluation, and summarize previously suggested treatment paradigms. Categories: Otolaryngology Keywords: chondromyxoid fibroma, cmf, sinonasal tumors, review of chondromyxoid fibroma Introduction And Background Originally described in 1948 by Jaffe and Lichtenstein, the chondromyxoid fibroma (CMF) is a neoplasm of cartilaginous origin [1] accounting for <0.5% of all bone tumors [2-4], with a slight male predominance [5]. Although more commonly found in the metaphysis of long bones, between 1-5% of CMF cases are reported to occur in the head and neck [5-6].

  • Epiphyseal Chondromyxoid Fibroma with Prominent Adipose Tissue: an Unusual Radiologic and Histologic Presentation
    A Case Report & Literature Review Epiphyseal Chondromyxoid Fibroma With Prominent Adipose Tissue: An Unusual Radiologic and Histologic Presentation Christopher Kragel, MD, Gene P. Siegal, MD, PhD, and Shi Wei, MD, PhD A B Abstract Chondromyxoid fibroma (CMF) is a rare benign tumor that typically develops in the metaphy- seal intramedullary portion of long bones. The tumor may extend into the diaphysis or, seldom, into the epiphysis, but purely epiphyseal lesions are extremely rare, with only 2 cases having been reported in the literature. In this article, we report the case of a 51-year- old African American woman.
